Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529388, here are decompositions:

7 + 529381 = 529388
31 + 529357 = 529388
61 + 529327 = 529388
151 + 529237 = 529388
271 + 529117 = 529388
337 + 529051 = 529388
397 + 528991 = 529388
421 + 528967 = 529388

Showing the first eight; more decompositions exist.
